Check for and replace blown speaker

I suspect that I’ve blown one of my speakers of my FP4.
I’d like to know if there is a good method to check for a blown speaker specifically and if I’m correct in thinking that I could by a new speaker, such as this one: Fairphone 4 Earpiece - Spare Part | Fairphone and replace the damaged speaker myself by following one of the repair guides available on this website.
Thanks in advance

If you haven’t done so yet, you can call * # * # 2 8 8 6 # * # * to access a large number of hardware tests. i think in your case you will need to look for AUDIO (which includes several microphone and speaker tests). You’ll need to figure out which speaker is the one in question here as there is an earspeaker as well as the external speaker (at the phone’s bottom end).
